Jan 30, 2020 (Therese Pettigrew) - The Taylor Beryl pegmatites are unzoned dikes enriched in boron and beryllium that intrude metamorphosed ultramafic rocks close to the Ghost Lake batholith (Breaks and Moore, 1992).

Jan 30, 2020 (Therese Pettigrew) - The host rock has been metasomatized to produce a phlogopite-tourmaline-holmquistite (lithium-amphibole) aureole within 30 cm of the southeast dike contact. The Taylor Beryl pegmatite dikes are characterized by local emerald, which formed intermediately adjacent to phlogopite-rich selvages in contact with metaultramafic host rocks (Breaks and Janes, 1991). The primary mineral assemblage of the dikes is beryl-muscovite-potassium feldspar-quartz-tourmaline-albite and the accessory minerals are oxide minerals, garnet and apatite. The dikes contain sporadic local zones (4 by 10 cm) of albite replacement. Electron microprobe compositions of minerals from Taylor Beryl pegmatites and ultramafic host rock - tourmaline, fluorapatite, columbite-tantalite, garnet and muscovite (Breaks et al., 2003).
